321 One-child policy reflection: Ping Zhi

3 things I found out
-I found out that although stopping at two children and stopping at one child are both child-control measures, they have different effects on the country.
-I found out that stopping at two children will allow the country to roughly maintain its population count, while stopping at one child will cause the country's population count to decrease.
-I found out that the consequences of child-control policies will have huge effects on the country, sometimes even causing the country to reverse the child-control measures, such as in the case of Singapore and China.

2 perceptions I have gained
-I have gained the perception that the one-child policy of China is causing the people of China to be unhappy, as there will only be one child to support his parents and grandparents, in some cases, his great-grandparents, and his income may not be able to support all family members. In this case, the family will require more children so that both children can share the burden of supporting all family members, including those who have retired.
-I have gained the perception that child-control measures will cause the aging population to increase rapidly, and this may not be good for the country, as this will be a sign that the population count of the country is decreasing, and there will be fewer manpower that will support the country and earn money for the country.

1 question I may have
-If the country knows that having child-control measures might later backfire, why are child-control measures still introduced?
